This fortress must have been of great strength, for it stood on a height above the River Wear; many coins, urns, altars and pieces of Roman pottery have been found, as well as the remains of a hypocaust of the heating system. Later, Binchester became one of the “vills” of the Earl of Northumberland who held it until 1420 when it passed to the Nevilles who finally forfeited it with other lands in 1569. As is to be expected, the moor itself offers little of historical interest but it is linked with the records of Kirk Merrington, Whitworth Old Park, Binchester, Byers Green and Tudhoe, all of which form a part of the early days of Spennymoor. All these villages had common rights on the moor but, as it became denuded by increasing flocks, some of the local people were induced to relinquish their rights and so, gradually, the common became the property of just one owner Merrington Priory. The Manor of Merrington belonged successively to the priors, monks and dean and chapter of Durham Cathedral.
